“Haley discussed her resignation with Trump last week when she visited him at the White House, two sources said. Her news shocked a number of senior foreign policy officials in the Trump administration.”

Haley had discussed taking a break from her position with Trump six months ago according to Axios. Trump told reporters on Tuesday that Haley is “welcome back at any time.”

In September, Haley defended Trump after the New York Times published an anonymous op-ed, which suggested that a “senior administration official” saw Trump as a threat to democracy in the United States.
